Silicon PV Cell Design and Solar Intensity Radiation Optimization for CPV Systems

Abstract The photovoltaic characteristics and the efficiency of real photovoltaic (PV) systems with solar radiation concentrators with the account of output power loss arising due to the internal electrical resistance have been investigated. The paper presents theoretical framework for calculating and optimization of functional and structural system parameters including the radiation concentration ratio and the contact system parameters of typical photovoltaic cells, particularly the resistance associated with the lateral current flow the contact grid electrodes within thin surface layers.
